Little John's Marine Service installed a Patrick Automatic Radar Leveling Mount on Dutch's boat "Scoundrel" recently.  LJ has the distributorship on this mount and has also added the capability to lower the entire assembly in cases of low bridge clearance or limited dock roof height.  The mount also lets you lower the angle of the radar to get a clearer view of objects close to you, such as when entering a harbor.  Check out the pictures of the installation at:
